1.2 Game Description
Description |
The Doomsday Project is a sub-series using the Operational Scale System (or OSS) and the game on the Battle for Germany in 1985 will be the first game of the Doomsday Project and the third game in the OSS family. It will cover that great battle that never happened between the Warsaw Pact and NATO in the main ground battle of that war that never was. Other games in the sub-series will include games on the battle for Norway, the Balkans, the Middle-East and the Far-East...as well as non-system games cover the global naval war and strategic nuclear war. All of which will mate together as a titanic game on World War Three. |

1.4 Explaining Predictions
For each of the predictions above, I used models that were trained on historical boardgamegeek data in order to predict the selected game. How did the model(s) arrive at their predictions? The following plot displays Shapley values to indicate what features were most influential for the model’s predictions. Anything in blue increased the model’s predictions, anything in red decreased the model’s predictions.
2 Finding Similar Games
What games are similar to The Doomsday Project: Episode 1 – The Battle for Germany? I compare the selected game to every other game on boardgamegeek based on its mechanics, playing time, complexity, and game type. The tables below display the games which had the most similar data to The Doomsday Project: Episode 1 – The Battle for Germany. The reported similarity is the cosine similarity between the selected game and all other games published before 2021.
This similarity score ranges from -1 to 1, where similarity of 1 indicates that games are exactly identical (a game will have a score of 1 with itself).
Note: This analysis does not look at a game’s ratings on BGG, publisher, artist, or designer - it focuses on finding similar games based on how they play, not how they are rated or by their theme.

2.3 Why Are Games Considered Similar?
I first ran a dimension reduction method (PCA) to identify the main points of variation for games on BGG. The first 25 components explained roughly 50% of the overall variation in the dataset, so I computed the cosine similarity between every game’s score on these 25 components.
2.3.1 Plotting All Games
The following plot shows every game on BGG plotted on the first two principal components of variation. I then highlight where the selected game and its nearest neighbors fall on these first two components.
2.3.2 Game Profiles
Similarity scores are based on 25 principal components - the next table displays the selected game and its neighbors profiles on each of these components.
2.3.3 Examining Components
What are these components? The following plot shows which features contribute the most to each component.
